Very few people believed it was a 17-year old that sang the smash hit Royals, and even more fewer believed that number when they saw her at the Grammys.

A lot of conspiracy theorists suggested there was foul play involved in Lorde’s age, and pictures of her looking as old as Beyonce at the Grammys didn’t exactly help her cause.

A blog named The Hairpin paid a whopping $17.02 to the New Zealand Department of Internal Affairs for a copy of the singer’s birth certificate. According to the document, Lorde, whose real name is Ella Maria Lani Yelich-O’Connor, was born Nov. 7, 1996.
